I'd agree with absolutely everything mentioned above.
There are two types of pilots out there; the ones that will be persistent, flexible and willing to tough it out, coping with the frustrations and knockbacks. Willing to take a few beatings, dust themselves off and go again. These are the ones that have the right attitude and that will make it to an airline.
Then there are the ones that don't... and with the exception of a very small few, they won't make it.
It's not an easy industry to be in, it's fickle, a good majority of owners are borderline sociopaths or bi-polar, and the going can be very tough. Working out remote is no cakewalk, but then again if you go in with an open mind and don't expect things to be like they are in the city, then it's also not really that bad and the friends you'll make will last a lifetime.
Getting a degree is a good idea either way, both as a backup and airlines often look on degree holders more favorably.
The number one rule with success in aviation (if you have the determination). Don't be a c*&7! It's a simple rule, but you'd be surprised how many people forget how small aviation is. If you don't know a guy/girl, one of your mates will!
